4 Claims. (Cl. 29973) The present invention relates to lawn watersprinklers, and has reference more particularly to the portable type ofsprinkler which is adapted to be attached to the end of a garden hose.

This application is a continuation in part of an application filed by mein the United States Patent Office on June 14, 1956, under Serial Number591,399, for Lawn Sprinkler.

The prior art reveals a number of diiferent types of water sprinklers,but most of these devices have the common fault of dispersing the fullforce of the water pressure simultaneously through a plurality ofnozzles or openings. This results in limiting the sprinkled area to arelatively small portion of the lawn, and necessitates the frequentmovement of the sprinkler to a new location.

The principal object of the present invention is to provide a watersprinkler which will spray a substantially larger area than conventionalsprinklers of a comparable size.

An equally important object is to provide a water sprinkler which isrelatively small and light in weight, and thus may be easily moved fromone location to another.

Another object is to provide a sprinkler of this class which features awater dispersing means for directing the full force of the waterpressure against a plurality of angularly adjustable spray nozzles inconsecutive sequence.

An additional object is to provide a sprinkler of this character whichhas only one continuously moving part to become Worn or get out oforder.

A further object is to provide a sprinkler of this class which includesa plurality of restrictive spray nozzles carried by the top of thesprinkler, which may be manually adjusted for spraying a desired area.

The present invention anticipates a hollow cylindrical body having alateral hose connection on a vertical axis and a pair of disks which arerigidly connected in spacedapart relation by a plurality of radiallyspaced vanes. The upper surface of the body is provided with a pluralityof circumferentially spaced-apart spray nozzles. Each of the nozzles hasa pivotally mounted discharge tip for selectively directing the waterangularly upward or outwardly from the body. As water enters the body,rotating the disks by means of the vanes, a recess in the periphery ofthe uppermost disk emits water through openings in the top incommunication with the spray nozzles as the recess uncovers and coversthe openings in rotative sequence.

Other objects will be apparent from the following description when takenin conjunction with the accompanying single sheet of drawings, wherein:

Figure 1 is a top view of the sprinkler;

Figure 2 is a vertical cross sectional view taken substantially alongline 2-2 of Fig. 1;

Figure 3 is a perspective view of the rotating disks and vanes, per se;

nited States Patent Figure 4 is an enlarged fragmentary vertical crosssectional view of the sprinkler top and one of the nozzles; and,

Figure 5 is a perspective view of one nozzle discharge tip, per se.

Like characters of reference designate like parts in those figures ofthe drawings in which they occur.

In the drawings:

The reference numeral 10 indicates the device, as a whole, whichcomprises, in general configuration, a substantially cylindrical hollowbody 12 having a closed upper end or top 14 and a lower end closed by abottom plate 16 removably connected to the body by screws 18. A tubularprojection 17 is integrally carried by the Wall of the body incommunication with its hollow interior for connection with a garden hose21. The top 14 is provided with a plurality of openings or perforations19 adjacent its periphery in circumferentially spaced-apart relation incommunication with the interior of the body 12.

As shown in Figs. 1 and 4, the top 14 integrally carries a circular base20 surrounding each of the respective openings 19. A discharge tip 22 ispivotally carried by each base 20 within a co-operating recess 24 formedin the base. The base members 20 may be formed separately from the top14, as illustrated in Fig. 2, and joined theretoin any suitable manner,if desired. Each of the discharge tips 22 comprises a relatively smallcylindrical section 26 having a cylindrical ejection end tip or spout 28integrally joined to the periphery of the section 26. An axial bore oropening 30 is formed in the ejection tip 28 which extends diametricallythrough the cylindrical section 26. The wall of the opening 30 isarcuately curved outwardly as it approaches the periphery of thecylindrical section 26, on the side opposite the tip end 28, to form aflared end opening 32, as seen in Fig. 4 and as is shown by dotted linesin Fig. 5. Stub axles 34, carried by the cylindrical section 26,pivotally mount the discharge tip 22 within the base 20 on a horizontalaxis perpendicular with relation to a diameter of the top 14. Thus, eachof the discharge tips may be adjustably pivoted manually to any positionbetween an outwardly directed position, with reference to the center ofthe body 12, as shown by solid lines Fig. 4, and an inwardly directedposition as is illustrated by dotted lines. The flared end 32 of the tipopening 30 thus receives the full force of water pressure within thebody 12 regardless of the positioning of the ejection tip 28.

A shaft or axle 36 is axially journaled by the top and bottom of thebody and rigidly carries an upper disk 38 and a lower disk 40 inparallel spaced-apart relation adjacent the inner surface of the top 14and bottom 16, respectively. The peripheries of the disks 38 and 40 areclosely received by the wall of the body 12. The disks are rigidlyinterconnected by a plurality of vertically disposed radially extendingvanes 42. The upper disk 38 is provided with a peripheral recess 44formed between one set of the vanes 42 which permits water underpressure to enter the body and to be ejected outwardly between the saidtwo vanes through the openings 19 and discharge tips or nozzles 22 inconsecutive order as the disks 38 and 40 are rotated. Thecircumferential extent of the arc encompassed by the recess 44 is suchthat it substantially spans the distance between two of the openings 19to prevent the disks and vanes stopping on dead center. Transversely therecess 44 is sufiiciently wide to uncover the lower end of each opening19, as is clearly shown in Fig. 2. The vanes 42 extend inwardly from thecircumference of the disks in angular relation with respect to theradius of the disks and end in spaced-apart relation from the axle orshaft 36 (Fig. l) to allow water entering the sprinkler to be directedbetween all vanes, and outward through the rerecess 44 and dischargenozzles 22, regardless of the position of the disks.

Obviously the lower disk 40 may be eliminated without altering theefiiciency or operability of the sprinkler.

Operation In operation the sprinkler is connected to a garden hose 21and the sprinkler placed in the desired location. Water under pressureenters the sprinkler from the hose and revolves the disks by means ofthe vanes 42, thus spraying water outwardly through the nozzles 22 asthe recess 44 is rotated. The screws 18 may be countersunk into thebottom in a conventional manner, if desired, thus permitting thesprinkler to be moved by dragging without entanglement with grass stemsor roots.

Obviously the invention is susceptible to some change or alterationwithout defeating its practicability, and I therefore do not wish to beconfined to the preferred embodiment shown in the drawings and describedherein, further than I am limited by the scope of the appended claims.
